Well Rogers is getting their network into shape for this through enabling channel bonding on their cable nods. D3 modems can take advantage of this to provide further upstream. There are already many Rogers customers who have gotten the higher upload speeds or just asked for it! »Rogers Upstream Bonding
Once Rogers rolls it out officially to their clients and updates their products TPIAs will also likely get the bump as it is Rogers that pushes the upgrades out. My guess so far as been that with so many reports of different areas of Ontario getting upstream bonding that ability to roll out the higher speeds can't be too too far away.
